Inventor: KITADA KAGEAKI
IPC: C23F1/02
Filed: 1990-06-01
Abstract: PURPOSE:To improve the adhesion between an Al thin-film layer and a resist layer and to form a fine pattern, by dipping an Al thinfilm layer deposited on a ceramic substrate in an acidic soln. contg. a fluorine compd. and a soln. of an org. chelate compd. at a specified pH to reform the surface. CONSTITUTION:The Al thin-film layer deposited on a ceramic substrate for PGA is cleaned, then dipped in an acidic soln. contg. 0.1-20wt.% of a fluorine compd. for about 5 sec to 5 min and washed with water. The layer is then further dipped in a soln. contg. 0.1-10wt.% of an org. chelate compd. and kept at pH 3-9 for about 5 to 10min to dissolve and remove fluorine ion, washed with water and then dried. Consequently, the surface roughness Ra of the layer is controlled to about 0.4-0.8mum, and the adhesion to the photoresist is improved. The surface of the layer is coated with a resist coating film layer which is pattern-exposed and developed to form a resist pattern, and then the layer is chemically etched. As a result, the precision of the resist pattern is improved, and a fine pattern is formed on the Al thin-film layer.

Title: Frame synchronizing device
Inventor: FUKAZAWA YASUO
IPC: H04J3/06
Filed: 1981-09-14
Abstract: PURPOSE:To realize a quick and automatic recovery to the normal state for a time division multiplex transmission line, by shifting immediately a comparing pattern generating circuit to a specific state when it is detected that the said generating circuit exists in an inhibition region. CONSTITUTION:The pattern of a 2<n>-1 pseudo random pattern generating circuit 2 having a higher operation speed than a comparing pattern generating circuit 1 is compared with the pattern of the circuit 1 through a comparator 3. Then a coincidence signal is fed to a resetting circuit 4 when the coincidence is obtained between both patterns. The decoders 5 and 6 which receive the pattern from the circuit 2 transmit signals (b) and (c) to an FF7. The FF7 feeds the inhibition region signal (d) showing an inhibition state to the circuit 4 in a period during which the FF7 receives the signal (c) after receiving the signal (b), i.e., in a period of a pattern state in the inhibition region where the circuit 2 is not used as a frame synchronizing pattern. When the circuit detects that the state of the circuit 1 is identical with the state of the inhibition region, the circuit 4 feeds the reset signal (e) to the circuit 1 to set the circuit 1 to a specific state.

Title: Fault detecting device
Inventor: ADACHI KAZUO
IPC: G01R31/08
Filed: 1982-08-19
Abstract: PURPOSE:To ascertain easily a steel tower in which a ground fault is generated, by deciding and displaying a ground fault of a transmission line by the direction of a current flowing to an overhead ground wire by making the steel tower a boundary. CONSTITUTION:If a ground fault is generated in a transmission line in a steel tower 2, currents 8, 9 flow out to an overhead ground wire 4 through its steel tower 2. By these currents 8, 9, currents 13, 14 are induced to CTs 10, 11. Current direction detectors 15, 16 detect these currents 13, 14, and send out a detcting signal to a logical circuit of a deciding device 18. In this case, since the currents 13, 14 flow in each opposite direction, voltage is generated across a resistance 17, therefore, the deciding device 18 responds and displays a fault. On the other hand, a current flowing to the overhead ground wire 4 of other adjacent steel tower 2 flows in the same direction by making its steel tower 2 a border, therefore, the deciding device 18 does not respond.

Title: Driving force transmitter for four-wheel-drive vehicle
Inventor: SAKAI TOSHIBUMI
IPC: B60K23/08
Filed: 1987-06-12
Abstract: PURPOSE:To maintain a constant torque transmitting force continuously so as to ensure escape from such a rough road as a muddy road or the like by designing a differential pump provided between front/rear wheel driving shafts in a variable capacity type and also in a temperature compensating style for controlling to increase eccentric quantity between a cam ring and a rotor according to a change in oil temperature. CONSTITUTION:At the time of escaping from a muddy road or the like, the continuation of large differential rotation for a long time sharply increases an oil temperature, thereby changing, in an extending state, the shape of a spring 27 made of a shape memory alloy and in contact with the oil increased in temperature. Therefore, a piston 25 is pushed by means of the spring 27 so as to advance, thereby pushing a cam ring 20 against the pushing force of another spring 23, and thereat, an increase in eccentric quantity between the cam ring 20 and a rotor 22 enlarges discharge flow rate. As a result, a change in viscosity caused by the increase in oil temperature enlarges a leak inside a pump, and then, substantial oil discharge of a differential pump 16 is kept at necessary fixed quantity despite of deterioration in the volumetric efficiency of the pump so as to be supplied to the oil chamber 15 of a hydraulic clutch 12. Therefore, without any change in torque transmission to a rear wheel driving shaft 11, four-wheel drive enables sure escape from a muddy road or the like.

Abstract: PURPOSE:To observe effectively some part of a reproduction picture by transforming a vertical sawtooth-like signal into a nonlinear shape by means of a vertical scan speed changing circuit, adding a stage-shaped DC component to a vertical deflection drive circuit by means of a DC component addition circuit and expanding a reproduction picture in the arbitrary direction. CONSTITUTION:A vertical sawtooth waveform signal from a vertical sawtooth wave generator 7 is transformed into a nonlinear waveform by a vertical scan speed changing circuit 9, and reset by plural frame periods by means of a DC component addition circuit 11 for comprising a raster erase device 10. Then a stage-shaped DC component is added to a vertical deflection drive circuit 12 by using one frame period as one step. Thus, since a deflecting current having different partial speeds, where DC components change by frame period at every n-frame periods, flows in a vertical deflecting system of a display tube of a television picture monitor 2, a piece of reproduction pictures are sequentially reproduced by adjoining rasters, whereby the reproduction picture with inconspicuous raster can be obtained. Simultaneously the picture becomes partially a high speed scan signal, which is expanded in the vertical scan direction.

Abstract: PURPOSE:To improve a yield rate in chip bonding and to make it possible to provide two dimensional array of chips, by forming a concave part in a substrate, forming an active layer and a clad layer in the concave part, forming a current blocking region in the region outside the external part of the side of the concave part so as to prevent current flow, thereby suppressing the spread of the current to the outside of the side surface of the concave part and taking out the light in the directon perpendicular to the chip surface. CONSTITUTION:A layer 2 is grown on a substrate 1 in a liquid phase. Then the concave part 3 is formed and the clad layer 4 and the active layer 5 are grown in a liquid phase. Then an N electrode 9 and a P electrode 10 are formed on the surface of the substrate 1, on which the layer 5 and the clad layer 8 are formed, and the surface of the clad layer 8, respectively. Then a light extracting windown 11 is provided. In this constitution, since the light in the direction perpendicular to a semiconductor chip can be taken out, the degradation of the yield rate of bonding due to the attachment or bump of a fused bonding material to the side of the chip in the bonding is alleviated, and the wiring can be readily performed even though the chips are arranged in the two dimensional array.
